background music and voice over playing at the same time in Windows Movie Maker

This is how to add background music while having a voice over at the same time. Windows Movie Maker only has 1 audio/music track but now you can have both playing and here's how! I am using an older version of Windows Movie Maker v 2.6 a free download: http://www.softpedia.com/get/Multimed... . The new Windows Live Movie maker doesn't come with a microphone.
